How to connect Wi-Fi to a TV if there is none: 5 proven methods

You bought a new router, updated your home network to Wi-Fi 6, but your TV stubbornly requires a cable? Or doesn't detect wireless networks at all? This problem is familiar to many: even modern Smart TV budget segment (for example, Xiaomi Mi TV 4A or TCL 4-Series) sometimes lack a Wi-Fi module, not to mention older models Samsung Series 5 or LG 32LN540BBut this isn't a death sentence—there are at least five ways to connect your TV to the internet wirelessly.

The main thing is to understand which method is right for you. If your TV supports LAN port, but doesn't have Wi-Fi, an adapter for 500-1500 rubles is sufficient. Even if there's no Ethernet port (as some CRT TVs with HDMI), will help Android set-top box or DLNA serverWe'll cover all options, from the cheapest to the most versatile, and explain how to avoid common setup mistakes.

Spoiler: Most TVs with an HDMI 1.4+ port can be connected to Wi-Fi via an external adapter even without firmware - you just need to choose the right device with support Miracast or Wi-Fi Direct.

1. Checking the technical capabilities of the TV

Before spending money on adapters, make sure your TV is wirelessly capable. Here's what to check:

• 🔍 TV model: Locate the sticker on the back (e.g. Samsung UE40J5200AK or LG 43UK6200) and check the specifications on the manufacturer's website. Look for lines like Wi-Fi: Yes/No or Wireless networks: Supported.
• 🔌 Availability of portsThe minimum set for connecting to Wi-Fi is HDMI (for prefixes) or USB + Ethernet (for adapters). If there is only AV/RCA, there are fewer options.
• 📱 Smart functions support: Go to the TV menu. If there is a section Net or Smart Hub, but there is no point Wi-Fi, this means that the module is physically absent, but the software is ready for connection.

Pay special attention to televisions with Android TV (For example, Sony Bravia X80J or Philips 7500 Series). Even if Wi-Fi doesn't work, a factory reset can often solve the problem (Settings → Storage & reset → Factory data reset). If the module does not appear after the reset, it is either broken or missing.

Critical moment: some televisions (eg. Sharp Aquos 2015–2017) have a hidden Wi-Fi module that is activated only after a firmware update. Check the software version in the menu. Support → Software Update.

2. Method 1: USB/Wi-Fi adapter for TV with Ethernet port

The easiest and cheapest method is to use USB-Wi-Fi adapter, if your TV has LAN port (Ethernet). Suitable for models Samsung Series 6/7, LG UK6300 and others with support USB 2.0.

How it works: The adapter plugs into the TV's USB port and emulates a wired Wi-Fi connection. The TV "thinks" it's connected to the router via a cable, but in reality, data is transmitted over the air.

• 🛒 Which adapters should I choose?:
  • TP-Link TL-WN725N (nano size, supports 802.11n)
  • Edimax EW-7811Un (compatible with most Smart TVs)
  • Asus USB-N10 Nano (works with LG WebOS And Samsung Tizen)
• ⚠️ Important: Not all adapters are compatible! Before purchasing, check the list of supported devices on the TV manufacturer's website. For example, Samsung officially recommends only Samsung WIS09ABGN (about 2000 rubles).

Unplug the TV for 1 minute.

Plug the adapter into a USB port (preferably 2.0)

Turn on the TV and go to Settings → Network → Network settings

Select Wireless connection (Wi-Fi)

Follow the instructions on the screen-->
